Trajectory patterns and factors influencing perinatal fatigue among Chinese women from late pregnancy to 6 months after delivery

Abstract

Background Perinatal fatigue among women is related to the clinical outcomes of mothers and infants. Perinatal fatigue changes over time, and the trajectory varies according to the predictors and outcomes of the mothers. This, however, has not been documented in any study. Objectives This study aimed to identify and characterize the trajectory patterns of perinatal fatigue among women from late pregnancy to 6 months after delivery. Methods We used growth mixture modeling to estimate the trajectory of perinatal fatigue at 28 gestational weeks (T0), 37 gestational weeks (T1), 3 days (T2), 1 week (T3), 6 weeks (T4), and 6 months (T5) after delivery with (n = 1,030). The Mann-Whitney U test and binary logistic regression were used to tie the selected trajectory classes to predictors and outcomes. Results There were two distinct patterns of perinatal fatigue in women: “persistently high” (11.1%, n = 114) and “persistently low” (88.9%, n = 916). Levels of perinatal fatigue among women in the “persistently high” group were higher than those in the “persistently low” group across the six measurements. Complications, fatigue at T0, and employment status in late pregnancy were all significant predictors of trajectories. Additionally, the “persistently high” group had a greater prevalence of difficult baby care and weight retention and a lower prevalence of exclusive breastfeeding. Conclusions Our study proved the heterogeneity and characteristics of perinatal fatigue among women. Future research should concentrate on developing intervention packages targeted at specific individuals in order to alleviate perinatal fatigue in women.

Postpartum stress in the first 6 months after delivery: a longitudinal study in Nantong, China

“…Taylor and Johnson62 found that perinatal fatigue reached the lowest level at 6 months after delivery, in line with our study. In another study, the lowest fatigue score was also observed at 6 months in the ‘perinatal fatigue persistently low’ group 63. This may be because the number of night wakings gradually stabilises at 6 months, thus gradually increasing the sleep duration at night 64.…”

“…In another study, the lowest fatigue score was also observed at 6 months in the 'perinatal fatigue persistently low' group. 63 This may be because the number of night wakings gradually stabilises at 6 months, thus gradually increasing the sleep duration at night. 64 This allows the mother to get better rest, reducing fatigue.…”
